HENRY HERMANI, OF BALTIMORE, MARYLAND, ASSIGNOR TO THE TIN DECORATING COMPANY OF BALTIMORE, OF BALTIMORE, MARYLAND, A CORPORATION OF NEW JERSEY.

Application filed March 16,

I or similar type, a hinged closure which is available for convenient use after the can has been initially opened, in order to properly retain or protect the contents until the latter is exhausted. Cans of this type are usually provided with an integral rip strip which is torn away in the initial opening of the can. A further object of the invention therefore, is to provide a suitable hinged closure in connection or combination with a can having a rip strip. I

The characteristics and advantages of the invention are further sufliciently. explained in connection with the following detail description of the accompanying drawing, which shows one representative embodiment of the invention. After considering this example, skilled persons will understand that many variations may be made, and I contemplate the employment of any structures that are properly within the scope of the appended claims Fig. 1 is a perspective view of the different parts embodying the invention in one physical -form, approximately positioned, to explain the mode of assembly.

Fig. 2 is 'a perspective view of the upperv part of the can or tin with the parts partially assembled.

Fig. 3 is a side elevation of the complete, sealed can, with some parts sectioned.

Fig. 4t,is a transverse vertical section.

I Fig. 5 is a fragmentary horizontal section.

Fig. 6 is a perspective view of the complete can with the rip strip in process of removal.

Fig. 7 shows the can completely opened by removal of theerip strip and with the hinged cover thrown back to give access to thecan contents.

The invention is especially designed or I adapted for approximately fiat cans which are intended for pocket use, being employed for example, to contain smoking tobacco n RIP-STRIP CAN OR CONTAINER..-

small quantities for pocket carrying and use of pipe smokers; and as here specifically cmbodied the invention is in the form of a flat tobacco can with rounded edge walls; but in the broader aspect of the invention it is not limited as to the size or cross sectional form of the can. I

The can body consists of a single body sheet 1, bent in flat tubular form with broad side faces 2 and rounded longitudinal edge walls 3, and secured in that form by the usual side seam 4. Parallel score lines 5 are made, preferably on the inner face of the sheet, before it is bent to body form, and one of the sheet edges isiformed with a projecting tongue 6, which is a continuation of the rip-strip defined by the lines 5, this tongue being left free against the outer wall for application of a rip key 7, Fig. 6. Usually the bottom of the body is left open for convenient filling, vacuum treatment and closure by the commodity producer or packer, the closure being effected by applicationofthe usual bottom cap 8 secured in position by a lock seam 9. This procedure is desirable because the top structure as now to be explained, is relatively complex, and

top filling and closure by the commodity producer or packer would be relatively difficult and expensive. This procedure can, however, be employed if considered necessary or desirable. I

A collar is provided, shaped and dimensioned to have a close sliding fit within the upper part of the body -1. In one of its broad walls 11, this collar is notched or cut to provide spaced hinge members 12, which are bent to eye form for the reception of a hinge pin. An inner cover member 13 is provided, of generally shallow, dished formation, and of outline conforming to that of the can body and collar, and adapted to fit closely within the upper portion'of the can body 1. This inner cover. includes a main, flat wall 14:, having an upturned marginal flange or wall 15, interrupted at 16 by a portion 17 which is cut 1 from the position there shown until the flange or wall of the hinged cover telescopes within the upper portion of the body and the slightly flared periphery 21 of the cover wall rests upon or is substantially flush with the upper edge of the body, as

7 shown in Fig. 4C. The collar may be secured cluding the top cap 40 in position in any suitable way, for example, by soldering; In the present example, preferred in some cases, the collar is secured by a crimping or beading operation, in which an outwardly convex bead 30 is formed in the lower margin of the collar,

vand at the same time a mating bead 31 is formed in the can body, to securely lock theparts together and at the same time provide a desirable outer appearance or finish of the can.

The outer or top cover cap 40 is then applied. This cap has a main wall 41 with a shallow side wall 42 terminating in a fiat peripheral flange 43. The side wall -42 is of course, conformed to the can outline and has a close push fit within the flange or wall 15 of the hinged cover 14. When so inserted the mainwall 41 of the cap lies on the main wall 14 or the hingedcover, and the flat flange 43 lies up on the upper edges of cover flange 15 and the body 1, and projects therefrom. The fiat flange 43 is then rolled over or crimped by pressing or spin ning operations to firmly clinch the edges of the hinge and the main body in final closed form, as best shown in Fig. 4:. The upper end or top of the can is thus -com pleted and hermetically sealed, and as above stated, the bottom cap 8 is usually left 05 so that the can may be filled with the desiredcommodity, vacuumized and capped, producing the complete package shown in Fig. 6, the rip strip, of course, being intact until removed by the consumer.

, Fig. 6 shows the rip key 7 applied to the projecting tongue 6 of the rip strip and revolved sufliciently strip upon 'the key and tear this portion away from the can body. When the strip is entirely torn ed the cover structure inand the hinged cover 13, secured together in the manner reviously described, is accessible and free or opening by a hinge movement, as shown in Fig. 7. The act of tearing the rip strip pro- 21 to facilitate the cap crimpthe rip strip,

a cap to wind a portion of the.

duces a shallow sidewall 50 now included namely, the upper margin of the body,

above'the rip-strip. This wall 50, when the cover is closed, overlies the upper marginof the collar 10; or otherwise stated, the collar telescopes within this wall. Therefore, when the cover is shut, the can contents is securely held, but is easily accessible when the cover is thrown back, as shown in Fig. 7 for removal of parts of the contents as often as desired, until the contents is exhausted.

.lt is especially to be noted that the closure construction is very compact and none of the available space defined by the dimensionsot the can body is wasted. In other words, the can has substantially the same cubic volume as an ordinary can of the same dimensions.

It is evident from the preceding description,, that an important function or the part 13, referred to as an inner coyer member,

is to provide one convenient and practical so that when the rip strip is torn 05 to in- Y' itially open the can, the cover, including the cap 40 and the 'fiange 50, remain in hinged connection to the body, for convenientuse as a movable closure. Prior to removal of however, the can top or cover (sometimes referred to as the cap) 40 is seam-connected and hermetically sealed to the body, forming a vacuum-retaining closure, and the hinge structure is entirely enclosed, without requiring any irregular formation or enlargement of the body, and occupies a negligible part of the contents: space. 4

I claim 2- 1. A can pr similar container comprising a tubular body wall having a rip strip defined therein near one end, a collar within the body wall and underlying the rip strip, a cover hingedly secured to the collar, an

seamed to the cover and body wall to form a tight closure which becomes a hinged cover upon removal of the rip strip, whereupon a portion of the body wall remains attached to the hinged cover and overlaps the upper margin of the collar when the covward portion of the collar, the collar having a hingeformation in one wall, a cover generally conforming to the cross sectional form of. the body and having a side wall 1, adapted to telescope therein and also having a hinge formation to co-operate with that of the collar, the edge of the cover side wall being substantially aligned with that of the body, and a cap interlocked with the edges of the cover and the body walls to permanently secure them together, so that when the rip strip is removed a remaining portion of the body wall is seamed to the cover structure and overlies the collar to form a tight closure openable by hinge movement to give access to the can contents.

3. A can having in combination a onepiece body and cover flange, comprising also a tearing strip integral with and arranged between the body portion and the cover flange portion, a collar secured to the body and extending past the tearing strip into the cover flange to provide a neck upon which the cover flange may seat when the tearing strip is removed, the collar having a hinge part, a cover part seamed to the cover flange, and a leaf having a hinge part cooperating with that of the collar secured to the cover and the cover flange by the seaming connection of cover and flange.

4:. A can having in combination a onepiece body and cover flange, comprising a1- so a tearing strip integral with and arranged between the body portion and the cover flange portion, a collar secured to the body and extending past the tearing strip into the cover flange to provide a neck upon which the cover flange may seat when the tearing strip is removed, the collar having a hinge part, a cover including a leaf having a hinge part cooperatin with that of the collar, and an upstan ing flange fitting within the cover flange, and a cup shaped member seated within the flange of the leaf and seamed to the leaf and cover flange.
